[Plugin: NextGEN Gallery] Albums displaying with no thumbnail

I have a problem that is nearly resolved, but there are a couple of issues that i can’t seem to sort.

I have 1 album that holds many sub-albums (so that i can display the sub-albums in the gallery page). Each sub album as many galleries.

My issue is that only 1 of my sub albums has a thumbnail from one of it’s galleries showing, also it correctly links to a page. However, none of the other albums show a thumbnail and only point to an ‘album’ page, not an actual wordpress page.

I must have got the settings right on the first album but cant for the life of me see how to set the others up. So my questions are.

1. how to get and album to show a thumbnail from one of it’s galleries.

2. how to get an album to link to an actual wordpress page that is set up, so that when i click on the album it will show the galleries in the correct page that i want, not just a nextgen gallery page.
